用药理学

1. cd20抗原人类CD20抗原是分化抗原(磷蛋白), 除亲b细胞和血浆细胞外, 几乎所有正常和致瘤b 细胞都表达, 在B细胞以外的细胞中不表达。

2. 抗肿瘤作用在与拉莫斯肿瘤细胞移植的小鼠肿瘤模型中, 观察到(90Y)伊布朱穆纳布-蒂奥克萨坦(重组) 具有肿瘤作用(体内)。

3. 作用机制伊布里佐穆单抗对B细胞上的CD20抗原具有较强的抗原特异性结合能力。作为一种螯合剂, Tiuxetan(与90Y 有强烈的结合), 在抗体中共价地与暴露在外的赖氨酸氨基和精氨酸结合。Yttrium(90Y)ibritzumab Tiuxetan(重组)与CD20抗原以及利妥昔单抗(重组) 结合, 诱导90Y 细胞凋亡和β射线释放, 诱导细胞毒性。

适应症

CD20阳性复发或难治性继发疾病低级b细胞非霍奇金淋巴瘤、地幔细胞淋巴瘤

英文版说明书

Company: Biogen IDECApproval Status: Approved February 2002Treatment for: Non-Hodgkin’s lymphomaAreas: OncologyGeneral InformationIn February 2002, Zeva lin was the first radioimmunotherapy to receive FDA approval. Zeva lin is indicated for the treatment of relapsed or refractory low grade, follicular, or transformed B-cell non-Hodgkin’s lymphoma (NHL). This indication includes patients with Rituxan (rituximab)-refractory follicular NHL. Zeva lin has been approved as part of a therapeutic regimen involving Rituxan.Zeva lin consists of a monoclonal antibody linked to the radioactive isotope yttrium-90. After infusion into a patient, the monoclonal antibody targets the CD20 antigen, which is found on the surface of mature B cells and B-cell tumors. In this manner, cytotoxic radiation is delivered directly to malignant cells.Clinical ResultsZeva lin received both a full approval and an accelerated approval based on results from two major US efficacy studies.The study that supported the full approval of Zeva lin included 54 subjects.The subjects were diagnosed with relapsed follicular lymphoma, and they no longer adequately responded to Rituxan treatment. An overall response rate of 74% was achieved with Zeva lin treatment, with 15% of subjects experiencing a complete response.Accelerated approval of Zeva lin was supported by a randomized, controlled phase III trial.The trial included 143 subjects with relapsed or refractory, low grade or follicular NHL or transformed B-cell NHL.An overall response rate of 80% was obtained in subjects receiving the Zeva lin therapeutic regimen (73 subjects), compared to 56% for the subjects receiving Rituxan alone (70 subjects). Thirty percent of Zeva lin-treated subjects experienced a complete response, compared to a 16% complete response rate for Rituxan-treatedsubjects.Side EffectsIn clinical trials, serious adverse reactions caused by the Zeva lin therapeutic regimen included infections, allergic reactions, and hemorrhage while thrombocytopenic. In addition, the development of myeloid malignancies and dysplasias have been reported.Adverse events that occurred in greater than 5% of subjects include(but are not limited to) the following:NauseaVomitingDiarrheaAnorexiaThrombocytopenia (decreased number of blood platelets)Neutropenia (decreased number of white blood cells)AnemiaArthralgia(joint pain)DizzinessDyspnea(difficult or labored breathing)Increased coughMechanism of ActionThe complementarity-determining regions of Ibritumomab bind to the CD20 antigen on B lymphocytes.Ibritumomab, like Rituximab, induces apoptosis in CD20+ B-cell lines in vitro. The chelate tiuxetan, which tightly binds In-111 or Y-90, is covalently linked to theamino groups of exposed lysines and arginines contained within the antibody.The beta emission from Y-90 induces cellular damage by the formation of free radicals in the target and neighboring cells.(from Zeva lin Prescribing Information)Additional InformationSchering AG has the marketing rights to Zeva lin outside of the United States.For more information on Zeva lin, please visit IDEC Pharmaceuticals.Additional information on non-Hodgkin’s lymphoma can be obtained through the National Cancer Institute.
